Demi Moore has enlisted the help of pop superstar Madonna as she prepares to begin her potentially tricky divorce proceedings from husband Ashton Kutcher. The couple will reportedly battle for their combined $240 million fortune, and the Hollywood actress is looking for all the advice she can get.The Queen of Pop, who reportedly used "spiritual guidance" as a means of getting through her divorce to Guy Ritchie, is said to be passing on some words of wisdom to friend Demi. A source told the UK's Metro newspaper, "She is calling Demi almost every day and sends her messages telling her to be proud of her strength and to know that she fought to make her marriage work". The singer is apparently using her experience of being with younger men to help Moore through the split from Ashton, a man 15 years her junior. The insider continued, "Madonna has had many younger boyfriends so she understands their mindset. She has told Demi that Ashton's immaturity is evident and that she deserves someone who will fulfil her intellectually and emotionally". After a stormy few weeks that has seen Ashton at the center of cheating allegations, Moore finally announced she is to divorce the actor. At the time, the Two and a Half Men star told Twitter followers, "I will forever cherish the time I spent with Demi.Marriage is one of the most difficult things in the world and unfortunately sometimes they fail. Love and Light, AK".Despite the split, Moore still remains known as "MrsKutcher" on Twitter, although fans have been advising her on ways to change the username.
